Ensiling Pretreatment of Banana Waste By-products: Influences on Chemical Composition and Environmental Rumen Biogas and Fermentation

The negative effect of waste from agricultural activities on man and animals had continued to be worrisome. This research inquired into the benefits of banana by-products silage (BBPs) supplemented with different substrates and urea. Samples of BBPs (banana peels, leaves, pseudostem and stalk) were cut, dried and bulked to formulate eight treatment (silage) groups namely; BBPs without additives (high moisture material 80–90%), BBPs treated with urea (2.5% of fresh weight), BBPs treated with wheat straw (20% of fresh weight), BBPs treated with wheat bran (20% of fresh weight), BBPs treated with alfalfa (20% of fresh weight), BBPs treated with wheat straw and urea, BBPs treated with wheat bran and urea and BBPs treated with alfalfa and urea arranged in a 2 × 4 factorial arrangement using completely randomized design. Results indicated that addition of different absorbents and urea significantly ( P
